Fig. 1. Variation in Phomopsis subordinaria infection prevalence in 260 Plantago lanceolata populations in the Ă…land Islands . A) The proportion of infected populations in the nine regional districts surveyed. The effect of host population B) size and C) connectivity on infection prevalence. D) The mean within-host infection load in infected populations measured as proportion of infected stalks within each infected plant. The pathogen within-population prevalence E) as the number of infected plants in the populations, and F) as the proportion of infected plants in the populations. G) The relationship between pathogen within-population prevalence in the population of infection and within-host infection load.
